Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 148388, here are decompositions:
- 7 + 148381 = 148388
- 109 + 148279 = 148388
- 139 + 148249 = 148388
- 181 + 148207 = 148388
- 241 + 148147 = 148388
- 367 + 148021 = 148388
- 439 + 147949 = 148388
- 577 + 147811 = 148388
Showing the first eight; more decompositions exist.

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 148,388 and was likely granted around 1873.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 148388 first appears in π at position 404,403 of the decimal expansion (the 404,403ordinal-suffix:rd digit after the integer 3).
Search range: the first 1,000,000 fractional digits of π. Any 6-digit-or-shorter string is virtually guaranteed to appear in there — the more interesting signal is the position.
